main body 14 includes a first opening S1, a second opening S2, abase 12, acasing 142, and asupport 143. Thebase 12 includes astand 124. The number of thestand 124 is at least three, which are configured in an equiangular manner to achieve a stable support. Thebase 12 is connected to thesupport 143 in various ways to support a display monitor of an electronic device. - The
casing 142 of themain body 14 encases thesupport 143 outside. The rotatingportion 13 and the adjustingportion 15 are configured in themain body 14, such as on thesupport 143, which is not limited. The rotatingportion 13 connects to the adjustingportion 15. The second opening S2 is disposed on thecasing 142. When thecasing 142 encases thesupport 143, a part of the adjustingportion 15 is exposed from the second opening S2, that is, a portion of the adjustingportion 15 is exposed outside themain body 14. - The adjusting
portion 15 drives the rotatingportion 13 to rotate when the adjustingportion 15 is driven by an external force. For example, a part of the adjustingportion 15 exposed from the second opening S2 is similar to a mouse wheel and is to be rotated by a user. The adjustingportion 15 is connected to the rotatingportion 13 in various ways. - For example, the adjusting
portion 15 and the rotatingportion 13 include gear structures at the connecting location, and when the adjustingportion 15 itself is rotated by a force, the gear structures of the both rotate together. Alternatively, the adjustingportion 15 is directly fixed to the rotatingportion 13, and when the adjustingportion 15 is rotated by a force, the rotatingportion 13 is rotated together. The connecting way of the adjustingportion 15 and the rotatingportion 13 described above is taken as an example and not for limitation. In embodiments, the adjustingportion 15 is rotated by the rotatingportion 13 in various ways. - The
light emitting portion 16 is disposed in themain body 14, and is adjacent to one end of themain body 14, for example, adjacent to the top of themain body 14. The first opening S1 is disposed on themain body 14, such as at the top of themain body 14, therefore, the light emitting portion 34 transmits a light through a first opening S1. In addition, thelight emitting portion 16 is connected to the rotatingportion 13. Therefore, when the rotatingportion 13 is rotated by the adjustingportion 15, thelight emitting portion 16 is rotated with the rotatingportion 13, that is to say, the adjustingportion 15 drives thelight emitting portion 16 through the rotatingportion 13 to adjust the angle of light. Thelight emitting portion 16 and the rotatingportion 13 are connected and rotated in various ways, which is not limited. - In addition, the
light emitting portion 16 includes aLED element 162, and theLED element 162 includes one or more light emitting diodes for emitting light when conducting. - In some embodiments, the projecting
device 10 further includes atop cover 18. Thetop cover 18 is disposed on the top of the projectingdevice 10 to cover the first opening S1 and is assembled with thecasing 142 to protect thelight emitting portion 16. Thetop cover 18 is made of a transparent material, which is not limited. - When a
graphic element 19 is disposed between theLED element 162 and thetop cover 18 of thelight emitting portion 16, the light emitted by theLED element 162 passes through thegraphic element 19 and thetop cover 18, and forms a projecting image on a target object, such as a wall or a ceiling (To make the explanation more clear, a projection image is formed on a wall or ceiling in the following example). In an embodiment, thegraphic element 19 is disposed on thetop cover 18, but in other embodiments, thegraphic element 19 is disposed on thelight emitting portion 16. The arrangement of thegraphic element 19 is implemented in various ways. For example, thegraphic element 19 is printed directly on thetop cover 18 or thelight emitting portion 16, or a transparent panel with thegraphic element 19 is clamped under thetop cover 18 or inside thelight emitting portion 16, which is not limited. The operation between thelight emitting portion 16, thetop cover 18, and thegraphic element 19 described above is only for example.

FIG. 3 is a schematic diagram of a projectingdevice 10 assembled with anelectronic device 30 according to an embodiment. Please refer toFIG. 1 to FIG. 3 . In the embodiment, theelectronic device 30 has adisplay monitor 20 and the projectingdevice 10. - The display monitor 20 is various types of displays, such as a display of a desktop computer, a display of a notebook computer, a display of a handheld electronic device, etc. The structure of the display monitor 20 belongs to the general technical field of the art and is not the focus in this embodiment, which is not described in detail herein.
- When the projecting
device 10 includes thesupport 143, the display monitor 20 is assembled with the projectingdevice 10, and thesupport 143 supports thedisplay monitor 20. The assembling location of thedisplay monitor 20 and the projectingdevice 10 includes a hinge structure, therefore, the position of the display monitor 20 is adjustable according to user's requirement. Since how the display monitor 20 assembling with the projectingdevice 10 belongs to the general knowledge in the art and is not the focus herein, it is not described here in detail. - By the collocation of the projecting
device 10 and theelectronic device 30, when the user operates theelectronic device 30, thelight emitting portion 16 emits a light, and the angle of the light is adjustable through the adjustingportion 15 to obtain a good atmosphere effect. -
FIG. 4A is a schematic diagram of an implementation of alight emitting portion 16 according to an embodiment. Please refer toFIG. 1 to FIG. 4 . In the embodiment, thelight emitting portion 16 is tilted disposed in themain body 14. When thebase 12 of themain body 14 is placed on a plane (such as a desktop), an angle (θ1) is formed between thelight emitting portion 16 and a horizontal line parallel to the desktop, and the light from thelight emitting portion 16 forms a projectingimage 40 on the wall. - In the embodiment, the
light emitting portion 16 is configured to form an angle (θ1) of at least 45 degrees with a horizontal line (Line1) parallel to the desktop. That is to say, the center path of the light emitted by thelight emitting portion 16 forms approximately the angle of at least 45 degrees with the desktop. When thelight emitting portion 16 is rotated, the angle (θ1) between thelight emitting portion 16 and the tabletop is changed, and the position of the projectingimage 40 on the wall is also changed together, for example, the position of the projectingimage 40 is moved from the wall to the ceiling. - In practice, when a user uses the
electronic device 30 in a sitting position, a portion of the user's field of view is blocked by thedisplay monitor 20, so that a visual blind zone (R1) is formed on the wall. If a part of the projectingimage 40 is in the visual blind zone (R1), the part of the projectingimage 40 is blocked by thedisplay monitor 20. When the angle (θ1) is at least 45 degrees, the bottom 42 of the projectingimage 40 on the wall is equal to or higher than the user's line of sight extends along the top of the display monitor 20 to the wall (that is, the top of the visual blind zone (R1)), and therefore the user is able to see the complete content of the projectingimage 40. -
FIG. 4B is a schematic diagram of another implementation of alight emitting portion 16 according to an embodiment. Please refer toFIG. 1 to FIG. 4A . In the embodiment, thelight emitting portion 16 is rotated through the adjustingportion 15. The angle (θ1) formed between thelight emitting portion 16 and the horizontal line (Line1) parallel to the desk is at most 135 degrees, that is, the central path of the light emitted by thelight emitting portion 16 is formed at most the angle of 135 degrees with the tabletop. When the angle (θ1) is 135 degrees, the projectingimage 40 is positioned on the ceiling and is located approximately in front of the top of the user's head, and then the user gets a full lighting atmosphere by easily seeing the projectingimage 40 while operating theelectronic device 10. - As shown in
FIG. 4A andFIG. 4B , when the angle (θ1) is 45 degrees, the position of the projectingimage 40 on the wall is a little higher than thedisplay monitor 20. When the user applies a force on the adjustingportion 15 to drive the rotatingportion 13 and thelight emitting portion 16, the position of the projectingimage 40 on the wall is changed and moved to the ceiling. - Please refer to
FIG. 3 ,FIG. 4A , andFIG. 4B . In an embodiment, a rotation range of the rotatingportion 13 is set to be 90 degree, which is not limited. Therefore, the angle (θ1) is range from 45 degrees to 135 degrees. The rotation range of the rotatingportion 13 is set in various ways. For example, a supporting structure (such as a protrusion or a slot) is disposed on or around the rotatingportion 13, so the rotatingportion 13 is prevented from rotating by the protrusion when the rotatingportion 13 is rotated to 90 degrees. Otherwise, a resisting structure is set on or around the adjustingportion 15 or thelight emitting portion 16 to limit the rotation range. The implementations are only for example and not limited herein. Since the focus here is the rotation range of the rotatingportion 13, any way to implement it is applicable, so it is not described in detail here. -
FIG. 5 is a schematic diagram of a corresponding implementation state of alight emitting portion 16 and a projectingimage 40 according to an embodiment. The figure is used to represent the correspondence between the angle (θ1) and the position of the projectingimage 40, and please refer toFIG. 1 to FIG. 4B at the same time. - As shown in
FIG. 5 , since the light emitted by thelight emitting portion 16 is not parallel to the desktop, the projectingimage 40 formed on the wall or the ceiling is deformed, which causes the original proportion to the projectingimage 40 is different from the proportion of the projectingimage 40. When the original proportion of thegraphic element 19 changes, the proportion of the projectingimage 40 also changes. Therefore, as long as the original proportion of thegraphic element 19 is not a normal proportion, the projectingimage 40 on the wall or the ceiling is able to show a normal proportion due to the non-horizontal light path caused by the angle (θ1). - In an embodiment, the original proportion (unnormal proportion) of the
graphic element 19 is inversely derived from the normal proportion of the projectingimage 40 through program engineering, such as restore engineering. In other embodiments, other methods are used to adjust the original proportion of thegraphic element 19 to make the projectingimage 40 to present a normal proportion. - Due to different users have different perspectives, usage habits, requirements for the projecting
image 40 are not the same, and changing of the position of theelectronic device 30 causes in the light path change. The user sets the adjustingportion 15 to adjust the angle (θ1) and the position or the proportion of the projectingimage 40 according to his/her requirements, therefore, the projectingimage 40 meets the requirements to get the best sound and light effects. - In addition, in an embodiment, except for adjusting the angle (θ1), the
light emitting portion 16 is configured to be horizontally adjusted in the same plane direction when the size of the angle (θ1) is fixed. - In an embodiment, the user manually applies force to the adjusting
portion 15 to change the position of the projectingimage 40 and finds a projection effect suitable for his viewing angle. In other embodiments, the proportion of thegraphic element 19 is automatically adjusted by the device itself. The following describes in detail the aspect of adjusting thegraphic element 19 by the device itself. -
FIG. 6 is a detail schematic diagram of an electronic device according to another embodiment. In the embodiment, theelectronic device 30 further includes adetector 52 and acontroller 54. Thedetector 52 detects a position information of the projectingimage 40 with respect to themain body 14, for example, detecting the size of the angle (θ1) , which is not limited. Thecontroller 54 is used to adjust the proportion of thegraphic element 19 according to the position information detected by the detector 42. - In the embodiment, the
graphic element 19 is disposed between theLED element 162 and thetop cover 18 in the form of an electronic dot pattern template so that thecontroller 54 is able to adjust the proportion of thegraphic element 19 at any time. For example, a small panel is disposed between theLED element 162 and thetop cover 18. The small panel is controlled by thecontroller 54 to change the displayed electronic dot matrix of thegraphic element 19, which is not limited. - In one embodiment, the
detector 52 is one of a variety of light detectors, such as a photosensitive diode to sense the light path. In one embodiment, the data of the light path sensed by thedetector 52 is processed by a microprocessor, such as executing a program to calculate the size of the angle (θ1), and handing over the calculated result to thecontroller 54. - In an embodiment, the
detector 52 itself or thecontroller 54 itself executes a program to calculate position information (such as the size of the angle (θ1)). In an embodiment, thedetector 52 and thecontroller 54 are disposed on a same integrated circuit, and the integrated circuit is disposed in the display monitor 20 or the projectingdevice 10. In an embodiment, thedetector 52 and thecontroller 54 are respectively disposed in different positions in theelectronic device 30. - By this, the user determines the position of the projecting
image 40 through the adjustingportion 15, and theelectronic device 30 automatically adjusts the proportion of the graphic element according to the size of the angle (θ1), which makes the projectingimage 40 automatically form a normal proportion. -

The structures of these elements themselves are similar to those inFIG. 1 to FIG. 6 , and the difference is that the projectingdevice 10' is presented in a modularized manner in this embodiment. For example, theelectronic device 30 and the projectingdevice 10' are integrally formed by the projectingdevice 10' being disposed directly in theback cover 22. - Therefore, in some embodiments, part of the projecting
device 10' is regarded as part of theback cover 22, so the first opening S1' and the second opening S2' are regarded as openings on theback cover 22. In addition, in other embodiments, theback cover 22 and the projectingdevice 10' are not integrally formed. The projectingdevice 10' is a separate module and is able to be directly removed from theback cover 22. - The light emitting mechanism of the
light emitting portion 16 is the same as the light emitting portion of the foregoing embodiment, which is described in detail. In addition, the projectingdevice 10' in this embodiment includes thetop cover 18, and the proportion of thegraphic element 19 is automatically adjusted by theelectronic device 30 itself. In other words, theelectronic device 30 ofFIG. 7 is capable to be applied to various embodiments of theelectronic device 30 ofFIG. 1 . - In sum, an improved
electronic device 30 is provided. Thelight emitting portion 16 is utilized to make the position and the proportion of the projectingimage 40 to meet the user's requirements and provide a good display effect, and then improve the user's sound and light feel. - Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention.
